Oxygen XML Forum

let's say I would like to target all `head` elements within a TEI XML document; I would normally use the expression for some unclear ( to me at least) reason and after performing some queries in the same session this query stopped working ; so I quit the app reopened the file but it still wouldn't work either on the xPath search nor when using XPath XQuery Builder instead whenever I ran a query I got the following pop up message

The XPath query returned no results. XPath scope: Current File

XML Refactoring still worked fine…

I created a new TEI All document using oXygen's file templates, but I still had the same issue

As I was digging in oXygen's forum I came across an old post and I tried the following expression which gave me the correct results

However I've never had to use a prefix before while using the file templates and sticking only to TEI, am I missing something super obvious? Is there a setting I should check?

Hello,

Normally XPath 2.0 expressions should be namespace-qualified when working with documents that have namespaces (like TEI). However, by default Oxygen tries to make XPath easier to use and is configured to use the default namespace of the root element in the document as the default namespace for XPath 2.0 expressions.
I'm guessing you have changed this option, menu > Options > Preferences, XML / XSLT-XQuery / XPath, XPath Default Namespace. For the default behavior it should be set to "Use the default namespace from the root element". Or you can press the "Restore Defaults" button from that option page. This affects both the XPath toolbar and the XPath/XQuery Builder.

Adrian

That was it… thank you!!
